Any line that intersects two parallel lines?

What is a transversal

100

If two parallel lines are cut by a transversal, these angles are on the inside of the two parallel lines and on the same side of the transversal.

What are Same Side Interior Angles (Consecutive Interior)

100
Two angles are congruent. The measure of the first angles is 42 degrees, what is the measure of the second angle
What is 42
100

If a pair of adjacent angles formed by intersecting line are linear pairs, what is their relationship

What is supplementary

100
If a transversal cuts two parallel lines, how many angle measures do you need to know to figure out all 8 angle measures in the figure.
What is 1.
200

Two angles whose measures add up to 180 degrees

What are supplementary angles

200

Two angles whose measures add up to 90o

What are Complementary Angles.

200
What is the relationship between angles 4 and 5?
What are Alternate Interior Angles.
200
One way to prove that lines are parallel lines is through understanding that corresponding angles are
What is congruent
200
If a transversal cuts two non-parallel lines, at least how many angles do you need to know to figure out all 8 angles in the figure?
What is 2.
300

When 2 parallel lines are both intersected by a transversal, these angles occupy the same position on the top and bottom parallel lines.

What are Corresponding Angles.

300

Two angels that form 90 degrees?

What are complementary 

300
If the measure of angle 8 is 112, what is the measure of angle 6?
What is 68.
300
To prove that lines are parallel one must understand that same side interior angles are
What is supplementary
300
If the measure of <1 is 4x-6 and the measure of <8 is 122, what is the value of x?
What is 4x-6=122 +6 +6 4x=128 x=32
400

Congruent angles formed by two intersecting lines

What are Vertical Angles.

400
If two parallel lines are intersected by a transversal these angles are located on the outside of the two parallel lines and on the same side of the transversal.
What are Same Side Exterior Angles.
400

What is the realtionship between angles 1 and 4?

What are Vertical Angles.

400
If the measure of angle 2 is 30o , what is the measure of angle 7?
What is 30.
400
If the measure of <3 is 150 and the measure of <6 is 3x, what is the value of x and what is the measure of <7?
What is <7=150; and 3x=150 x=50
500

When 2 parallel lines are both intersected by a transversal these angles are inside of the two parallel lines and on opposite sides of the transversal.

What are Alternate Interior Angles.

500

Lines that do not intersect.

What are parallel lines

500
If the measure of anlge 1 is 37o, what is the measure of angle 8? What is the angle relationship
What is 37, Alternate Exterior
500
Given that l || m, m<1=98°, then the measures of <3 and <8 are:
What is 82 and 98 respectively
500
If the measure of <4 is 8x+35 and the measure of <6 is 2x+5, then find the value of x and find the measure of <8?
What is 8x+35+2x+5=180 10x+40=180 10x=140 x=14 Now plug into <4 because it is congruent (corresponding) to <8. 8(14)+35=112 so <8=112.
